1. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application uses the ADO.NET Entity Framework to manage customer and related order records. You add a new order for an existing customer. You need to associate the Order entity with the Customer entity. What should you do?

D) Use the Attach method of the ObjectContext to add both Order and Customer entities.

2. You are designing an ASP.NET Web Forms application that uses a database containing user names and
hashed passwords for authentication. The Web application includes a login form in which users type their
user names and passwords.
You need to design a strategy to ensure that the user's login credentials cannot be stolen through a man-
in-the-middle attack.
Which approach should you recommend?

A) Install a certificate on the Web server, and force the login form to use SSL.
B) Write an onSubmit JavaScript handler that hashes the password before the password is submitted to the server.

public ActionResult Edit(int id)
{
return View(SelectUserToEdit(id));
} public ActionResult Edit(Person person) { UpdateUser(person); return RedirectToAction("Index"); } The first Edit action displays the user whose details are to be edited, and the second Edit action is called when the Save button on the editing form is clicked to update the user details. An exception is thrown at run time stating that the request for action Edit is ambiguous. You need to correct this error and ensure that the controller functions as expected.
